Common lead-acid batteries may be the default storage on smaller less expensive systems, and those in shallow water, but they may be the most expensive option available. I figure that with daily deep exercise, you can count on each battery wearing out past the economical recharge point every year. So with 12 batteries, on average you will be budgeting a $100 battery each month.
There's been good work the last 10 years on flywheel storage.
And there's the olde heavy weight on a cable wrapped around a drum that turns a generator. A company in California has small electric locomotives on a track up a mountain side, use cheaply billed power to drive them up, they generate power "falling" back down. The solid version of hydropower. How about 100 tons on a 1000ft chain to passively stabilise and provide power for a seastead?

Car batteries, yes. Not designed for deep cycle. Proper deep cycle batteries generally last their design lifecycle, about 5 years. Another storage option: www.buoyant-energy.com/english/principles-and-variations.htmlThe basic principle of Buoyant Energy (buoyant hydraulic energy storage system) is based on the well-established technology behind pumped hydro energy storage plants. The major difference is the arrangement and location of reservoirs at such plants. While conventional pump hydropower storage plants consist of an upper and a lower reservoir, Buoyant Energy uses a buoyant platform. The energy is stored solely through the potential energy of the mass of the floating structure. In order to store energy, water is pumped out (air is pumped in). As a result, the floating structure rises. In order to release the energy, the structure is lowered and the inflow into the smaller reservoir powers a turbine (turbine mode).
